Problems caused by Pollution Putrefaction of organics generation of methane and hydrogen sulfide gas. Bad odor. BOD and COD.Growth of pathogenic bacteria- DiseasesWaters with BOD cannot be used for irrigation since plant roots need molecular oxygen. Breeding of Mosquito larvaeContamination of ground water.

Problems ..Proliferation of blue green algae.Drop in fish growth.Pollution in Oceans helps growth of dinoflagellates (red tides) and jelly fish not finfish.Water cannot be used for drinking or other purposes without treatment

CLEANING POLLUTED WATERS

Current methods of treatmentNo treatment : Anaerobic bacteria generate Hydrogen sulfide gas and methane- Stink-- Nitrates , nitrites and organics in ground water.Treatment: Sewage treatment plantsAerators Oxygen --Activated sludge process Aerobic bacteria Sludge removalInvestmentPower--Running cost--Capacity restriction--Location and land

Nualgi Technology

11LTR1 LITRE NUALGI FOR 4 MILLION LITRES OF WATERPhotosynthesis

Diatom Algae grows in waterAerobic bacteria breaks down organicsZooplankton and fishes clean up the water body.Produces pure oxygen by Photosynthesis under water

Nualgi Technology - BenefitsCleaning polluted lakes, rivers, OceansGlobal carbon sequestrationRepopulating rivers and Oceans with fish.Mosquito controlBoosting low cost and high productive agriculture.Growing nutritious food and health benefits.

Nualgi treatment of sewage polluted lake

Case Study Of Nualgi Based Treatment atSahibabad Drain, Ghaziabad, India Started On 8/10/2015 for 3 months

Sahibabad Drain @ Brij ViharDosing of Nualgi (Diluted in water)

Observations post DosingBubbles of oxygen rising to the surface and creating ripples on the surface

Sludge at the bottom tends to rise to the top and break down due to aerobic bacteria

Other typical casesOoty lake treatment is done with Nualgi LakesExporting to USA where Lake savers and Clean flo are using this technology to treat lakesTreatment of domestic effluents of 6 lakh litres / day in Brigade Gateway Bangalore using Nualgi technology in existing ETP in the cellar. Blowers have been switched off and output tested meets pollution control norms. LED lamps used for photosynthesis. Questions?
